Procedures for transportation workplace drug and alcohol testing programs. Final rule

The Department of Transportation is amending certain provisions of its drug and alcohol testing procedures to change instructions to collectors, laboratories, medical review officers, and employers regarding adulterated, substituted, diluted, and invalid urine specimen results. These changes are intended to create consistency with specimen validity requirements established by the U.S. Department of Health and Human Services and to clarify and integrate some measures taken in two of our own Interim Final Rules. This Final Rule makes specimen validity testing mandatory within the regulated transportation industries.     

Exemption of certain systems of records under the Privacy Act. Final rule

This final rule exempts four systems of records (SORs) from subsections (c)(3), (d)(1) through (d)(4), (e)(4)(G) and (H), and (f) of the Privacy Act pursuant to 5 U.S.C. 552a(k)(2): The Automated Survey Processing Environment (ASPEN) Complaint/ Incidents Tracking System (ACTS), HHS/CMS, System No. 09-70-0565; the Health Insurance Portability and Accountability Act (HIPAA) Information Tracking System (HITS), HHS/CMS, System No. 09-70-0544; the Organ Procurement Organizations System (OPOS), HHS/CMS, System No. 09-70- 0575; and the Fraud Investigation Database (FID), HHS/CMS, System No. 09-70-0527.     

Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger

The Meisenheimer anions formed from TNT in KOH solutions in alcohol or acetone were used in screening tests for TNT among possible nitro-explosives. The same reaction was used for the spectrophotometric assay of TNT in soil by CRREL (Cold Regions Research & Engineering Laboratory of the U.S. Army) method, also known as Jenkins' method, but the color stability was too dependent on the solution composition and the water tolerance was low, necessitating complete drying of soil samples (which may cause partial analyte decomposition) prior to analysis. This study reports the development of a colorimetric method based on the solid phase extraction (SPE) of the Meisenheimer anion formed from TNT and aqueous NaOH into a strongly basic anion exchange resin Dowex 1-X8 (OH(-) form). The orange-red color that developed both in the solid resin and solution phases was persistent for at least 1h. The resin was let to swell in alcohol, washed first with 1M aqueous NaOH, and then with H(2)O before use. To 5 mL of 4-400 ppm TNT solutions in 1:1 (v/v) acetone-water, 0.5 mL of 5% NaOH was added, diluted to 50 mL with 1:1 acetone-water, and the resulting solutions (containing the orange-red Meisenheimer anion of TNT) were agitated at room temperature with 0.9 g resin for < or =50 min. TNT exhibited a reasonably constant distribution coefficient between the resin and aqueous phases. The absorbance of the filtered solutions was measured against a reagent blank at 500nm. The TNT-loaded resins were regenerated with 1M HCl containing sodium sulfite. The calibration line of filtrate absorbance versus analytical concentration was linear over two orders of magnitude between 0.4 and 40 ppm TNT in final solution. Unlike Jenkins' method, the method was tolerant to 100-fold (by mass) of common soil anions like sulfate, nitrate, and chloride. The basic advantages of the developed colorimetric method over the similar CRREL/Jenkins' method may be summarized as color stability, water and common ion tolerance, lowering of the LOD, and widening of the linear range. As opposed to Jenkins' method, the charge-transfer bands characteristic to colorimetric detection were not obscured by the presence of water. The method is suitable for on-site applications, because the color developed in heterogenous solution was stabilized, and the method can be easily practiced with a portable colorimeter to large numbers of samples.     

我国大学办学理念的偏失及矫治

大学办学理念是人们对大学的精神、使命、宗旨、功能以及价值观等大学发展基本思想的整体概括,它指导着大学的远景规划和发展方向。目前,我国大学办学理念存在着盲目攀高求大、学人重官轻术、办学过于世俗化、学术管理政治化、重科学教育轻人文精神养成等现象,这些严重阻碍了大学培养人才、创造知识、引导社会发展的使命的实现。大学应根据自己的历史和现实条件准确定位,树立自己的理想,构建全人教育、学术自由、引导社会发展的理念,以便为社会的文明进步担负起更大的责任。     

World Judicial Experts Discuss Strategies for Eradicating Violence Against Children——Summary of lntergovernmental Experts Meeting in Bangkok

From February 18-21, 2014, a panel of experts, which was established by a resolution of the United Nations Economic and Social Council to draft exemplary strategies and implementation measures for eradicating violence against children in crime prevention and criminal judicature, convened in Bangkok, Thailand, for an intergovernmental experts meeting mainly to discuss the draft. After general discussion, delib- eration by the presidium and detailed negotiations, the meeting produced the report, ＂Exemplary Strategies and Implementation Measures for Eradicating Violence Against Children in Crime Prevention and Criminal Judicature.＂     

中国道路十章——马克思主义中国化经典文献回眸(一、二)

站在二十一世纪第二个十年的起点,回望马克思主义在中国的发展,检视中国共产党引领中国人民走过的九十年的这条道路,总让人心潮难平,感慨万千。概括和描述这条道路,可以有多种方式。我们选择的,是镌刻在每一个十字路口、每一个历史的拐弯处一篇篇凝聚着中国共产党人心血和智慧的重要文献,它们仿佛一块块路标,指示着前进的方向。它们前后承接的足迹,正是马克思主义中国化道路的路线图。本文以中国近代以来的历史发展为大背景,对马克思主义中国化的一些经典文献进行解读和回顾,拟分五期连载,希望对理解和思考中国道路有所助益。
